SECTIONAL HULL cons'rnnc'rron.

Specification of Letters Patent.

Application filed February 3, 1922. Serial No. 533,778.

To all whom it may concern Be it known that we, FREDERICK SAMUELCRossLEY, a subject of the King of Great Britain, residing in Blackrock,Dublin, Ireland, and FREDERICK WILLIAM CRossLnY, a subject of the Kingof Great Britain, residing in Blackrock, Dublin, Ireland, have inventedcertain new and useful Improvements in Sectional Hull Constructions, ofwhich the following is a specification.

This invention relates to the construction of the hulls of boats, bargesor other vessels and whilst particularly adapted for boats or vessels ofthe so-called. welded type may also be used with boats or vessels inwhich the plates are bolted or riveted together. I

The present invention has for its object certain improvements designednot only to reduce the cost of construction but to enable theconstruction to be carried out more expeditiously than with the presentsystems of construction.

Boats or vessels constructed according to this invention, moreover,possess the advantage that a considerably increased carrying capacitymay be secured as compared with vessels of the samedraught of ordinaryconstruction, together with a greater cubic capacity. 7

With a vessel constructed according to this invention when the platinghas been assembled and welded or otherwise connected the structure soproduced is of much greater strength than with ordinary sys-' ferred tothereby forming a continuous tems of welded construction.

According to this invention instead of the usual frame or ribs, to whichthe plates are secured, plates are employed which may be of rectangularor other outline having flanges upon all sides said flanges, when theplates are assembled, being welded or'otherwise connected, replacing theusual ribs.

In order that the invention may be better understood drawings areappended in which Fig. 1 is a perspective view showing one form of plateaccording to this invention.

Fig. 2 is aperspective view showing four of the plates for the bow.

Fig. 3 is a similar view showing three of the stern plates.

Fig. 4 is a perspective view shoyving a form of plate whereby the beamof the vessel may be increased.

Fig. 5 is a perspective view showing an alternative form of plate.-

Flg. 6 is a plan showing the arrangement of plates shown in Fig. 5 whenassembled.

Flg. 7 is a perspective view showing a modlfied form of plate to thatshown in Fig. 5. Fig. 8 is a plan showing plates accordmg to Fig. 7assembled. i

F1g. 9 is a perspective view showing a further modification.

Fig. 10 is a plan showing a number of plates such as shown in Fig. 9assembled.

Fig. 11 is a perspective view showing a means for strengthening thekeelson.

Fig. 12 is a view showing a modified form' of plate embodying thekeelson.

Referring to Figs. 1 to 3 of the accompanying drawings a indicatesgenerally sec tions formed of sheet metal each of such length as toextend from the keel to the deck and provided upon their sides andcombing. The upper end of the plate may, however, be bent to any othercross-sectional outline. As applied to the formation of the bows twosuitably shaped plates are employed such as shown in Fig. 2 each formingone side of the said bow and provided with flanges a upon all theiredges. The stern sections are shaped as shown in Fig. 3 an end platesuch as 6 being provided.

In constructing the barge the various sections are assembled with theflanges. a abutting and may be temporarily orpermanently connected bymeans of bolts or when Patented June 6, 1922.

connected the abutting surfaces may be welded together the flangesforming re spectively the ribs, keelson and deck stringers. In order tostrengthen the keelson at the point where the ribs meet a hollow crossor T-shaped body such as b Fig. 11, may be provided designed to straddlethe flanges and which may be bolted or otherwise secured thereto.

In order to increase the beam. without altering the dimensions of thesections rectangular shaped stampingsor forgings, such as 0, shown inFig. 4', may be employed and which stampings or forgings are placedbetween the lower ends of the sections, the flangest-hereof beingsecured to the flanges of the said sectionsthereby forming a doublekeelson. The length of the par-ts c is equalrtothe width of: thesectionsand said plates or the like have marginal flanges similan to flanges a.

The sections may either: be arranged in alignment upon theopposite sidesof the vessel orthey may bearrangedso-tha-t they are staggeredAccordingto the modification shown in Figs. 5 and 6 the end of eachplate is cut away as shown: at c leaving air-extension 0 extend ing fromone side ofthe plate to the centre of said'plate or thereaboutsTheplatesare provided with. flanges a and whenassembled.the-projectionsof the plates upon-one side engage the .cutaway portions ofthe plates upon the other side as shown inFig. 6. Theplates may be intwo parts the meeting ends of the plates'being cuti awayand flanged as just described;

Preferably the side flanges are increased in width for the'purpose ofincreasing the strength of theribs at the point 00.

In order to increase the beam, plates may be employed'as shown by thedottedlines- (Z in. Fig; 5 said plates beingshaped'as shown and: beinginserted between the ends of the plates.

Instead of beingrectangular the ends of the, plates may be of. V-shaped'outline, as

shown-in Figs. 7 andS, said plates having all roundgthein flanges (R.

In order to increase the beam, quadrilateral or. triangular plates, asshown in Fig. 9, flanged upon all sides may be employed said-platesbeing arranged as shown in Fig. 10. Angle or other bars,,such asshown'by the dotted lines: 6 maybe employed.

A similar arrangement may. be employed where-the platesare made-in twoparts, as shown inv Fig. 7. Y v

In Fig 12 .there-iseshown a plate-designed to be used as part of thestructure or for increasing; the beam of the vessel.

T-his platae which is of, any suitable.

width, has acorrugation. or; depression y running longitudinally (whenassembled) through its centre. The width of the corrugation may beapproximately half the length of the side of the plate and it may be ofany suitable depth.

This plate, when assembled, forms, by means of its corrugation, ascupper running throughout the entire length of" the hull, greatlyfacilitating drainage. his corrugationor. depression forms, when theplates are assembled", a keelson which gives rigidity andstrength to thestructure.

' Other-and smaller corrugations maybe provided. for strengtheningpurposes as shown by the dotted lines 2, .2

In order to secure greater strength the plates may be provided withtongues adapted to overlap the adjacent surface of the-adjoining plateor engage recesses or indentations in: the flanges. those 'justreferred: to are shown; by dotted lines it in Fig; 1'.

It is obvious that various modificationsmay be made both in the shape'ofthe. ends of the plates and in the manner in which 2.

5. In ship hull construction including aset of plates having peripheralflanges grouped with an angle of each plate at a common point, and asecuring member having channelled arms radiating from said point andengaging the flanges of adjacent plates.

In testimony whereof we have hereunto set our hands and aflixed ourseals in the 15 presence of two witnesses.
